Mirror's Edge is one of the best games I've ever played. I see it as the next generation of platforming. I got the game for full price, and every penny was worth it. Sure, I beat it in probably 8 hours or so, but you gotta sometimes look at the quality, not the quantity. Would I rather play an average game for 20 hours, or a fantastic title for 10? I prefer the latter. A game does not have to be long to be worth the money, just like other titles like Ico, Shadow of the Colossus, and Prince of Persia the Sands of Time.
